# signal-promise

Simple wait/notify promise with optional max wait time

```

npm install signal-promise

```

## Usage

``` js

const Signal = require('signal-promise')

const input = new Signal()

process.stdin.on('data', function () {

  input.notify()

})

while (await input.wait()) {

  console.log('someone typed!')

}

```

## API

#### `s = new Signal()`

Make a new signal

#### `await s.wait([maxWaitTime])`

Wait for someone to call notify. If you specify `maxWaitTime`

the promise will resolve after `maxWaitTime` ms if no notify call has happened.

As a convenience the promise resolves to `true` so it's easy to use it as a condition.

#### `s.notify([error])`

Notify everyone waiting. If you pass an error the wait promise

will reject with that error.
